芭蕾舞演员 :如何通过电子邮件发送附件

Question

我正在使用wso2/gmail包发送电子邮件通知。根据文档(https://central.ballerina.io/wso2/gmail(，我们可以通过包裹发送带有邮件的附件。但是，当我尝试将附件路径定义为参数时，出现如下错误。

incompatible types: expected 'wso2/gmail:0.9.7:AttachmentPath', found 'string'

什么是附件路径类型？我们可以将附件路径的字符串数组解析为附件路径吗？这是我发送邮件的函数。

import wso2/gmail;
import ballerina/io;
import ballerina/log;
import ballerina/config;
import ballerina/http;
function sendErrorLogMail(string senderEmail, string recipientEmail, string subject, string messageBody) returns boolean {
endpoint gmail:Client gmailErrorClient {
clientConfig:{
auth:{
accessToken:config:getAsString("gmailApiConfiguration.accessToken"),
refreshToken:config:getAsString("gmailApiConfiguration.refreshToken"),
clientId:config:getAsString("gmailApiConfiguration.clientId"),
clientSecret:config:getAsString("gmailApiConfiguration.clientSecret")
}
}
};
gmail:MessageRequest messageRequest;
messageRequest.recipient = recipientEmail;
messageRequest.sender = senderEmail;
messageRequest.subject = subject;
messageRequest.messageBody = messageBody;
messageRequest.contentType = gmail:TEXT_HTML;
//What is the attachment path?
AttachmentPath attachmentPath = "./org/wso2/logs/loginfo.txt";
messageRequest.attachmentPaths = attachmentPath;
var sendMessageResponse = gmailErrorClient->sendMessage(senderEmail, untaint messageRequest);
string messageId;
string threadId;
match sendMessageResponse {
(string, string) sendStatus => {
(messageId, threadId) = sendStatus;
log:printInfo("Sent email to " + recipientEmail + " with message Id: " + messageId + " and thread Id:"
+ threadId);
return true;
}
gmail:GmailError e => {
log:printInfo(e.message);
return false;
}
}
}

Answer 1

是的。正如@pasan所提到的，AttachmentPath是一个记录。如果有人想引用，以下是更新的代码。

function sendErrorLogMail(string senderEmail, string recipientEmail, string subject, string messageBody) returns boolean {
endpoint gmail:Client gmailErrorClient {
clientConfig:{
auth:{
accessToken:config:getAsString("gmailApiConfiguration.accessToken"),
refreshToken:config:getAsString("gmailApiConfiguration.refreshToken"),
clientId:config:getAsString("gmailApiConfiguration.clientId"),
clientSecret:config:getAsString("gmailApiConfiguration.clientSecret")
}
}
};
gmail:AttachmentPath attachmentPath= {
attachmentPath:"./org/wso2/logs/loginfo.txt",
mimeType:"Text/plain"
};
gmail:MessageRequest messageRequest;
messageRequest.recipient = recipientEmail;
messageRequest.sender = senderEmail;
messageRequest.subject = subject;
messageRequest.messageBody = messageBody;
messageRequest.contentType = gmail:TEXT_HTML;
messageRequest.attachmentPaths = [attachmentPath];
var sendMessageResponse = gmailErrorClient->sendMessage(senderEmail, untaint messageRequest);
string messageId;
string threadId;
match sendMessageResponse {
(string, string) sendStatus => {
(messageId, threadId) = sendStatus;
log:printInfo("Sent email to " + recipientEmail + " with message Id: " + messageId + " and thread Id:"
+ threadId);
return true;
}
gmail:GmailError e => {
log:printInfo(e.message);
return false;
}
}
}

AttachmentPath

在[wso2/gmail][1]中定义为记录。attachmentPaths字段需要一个此类AttachmentPath对象的数组。所以以下应该有效。

gmail:AttachmentPath attachmentPath= {
attachmentPath:"./org/wso2/logs/loginfo.txt",
mimeType:"text/plain"
};
messageRequest.attachmentPaths = [attachmentPaths];
